提出了一种基于Sagnac环调制器和偏振相关调制的光子辅助微波混频器，并进行了实验验证。在该方案中，一个双并联马赫-曾德尔调制器（DPMZM）被纳入一个Sagnac环，其中光是单边带（SSB）调制沿着一个方向没有调制沿着相反的方向，由于在DPMZM的行波速度失配。将传播方向相反、偏振方向正交的SSB调制光和未调制光载波（OC）通过偏振合束器合束，得到部分正交的SSB调制信号，再通过偏振控制器注入马赫-曾德尔调制器（MZM），使未调制光载波的偏振方向与MZM的横电主轴（TE主轴）平行。因此，只有OC被数据调制，并且一阶边带直接通过MZM而没有基于MZM的偏振依赖性的调制。经过偏振器的偏振干涉和光电探测器的光电转换，获得相位稳定的微波信号。通过调整MZM的偏置点，实验获得了清晰的眼图，以及8 GHz的1 Gb/s开关键控（OOK）、幅移键控（ASK）和二进制相移键控（BPSK）信号波形。
A photonic-assisted microwave mixer using a Sagnac-loop-based modulator and polarization-dependent modulation is proposed and experimentally demonstrated. In this scheme, a dual-parallel Mach-Zehnder modulator (DPMZM) is incorporated in a Sagnac loop, where light is single-sideband (SSB) modulated along one direction with no modulation along the opposite direction due to the traveling-wave velocity mismatch in DPMZM. The SSB-modulated light and unmodulated optical carrier (OC) with opposite propagation directions and orthogonal polarizations are combined via a polarization beam combiner, and thus, a partial orthogonal SSB-modulated signal is obtained, which is then injected into a Mach-Zehnder modulator (MZM) via a polarization controller to ensure the polarization of the unmodulated OC paralleling with the transverse electric (TE) principal axis of MZM. Thus, only the OC is modulated by the data, and the first-order sidebands pass through the MZM directly without modulation based on the polarization dependence of MZM. After a polarizer for polarization interference and a photodetector for optical-to-electrical conversion, a phase-stable microwave signal is obtained. By adjusting the bias point of MZM, clear eye diagrams, and waveforms of 1 Gb/s on-off keying (OOK), amplitude-shift keying (ASK), and binary-phase-shift keying (BPSK) signals at 8 GHz are experimentally achieved.
